Thermocouple Wire
The materials that make up thermocouples are essential to ensuring that these products are properly matched to the application and provide the highest levels of accuracy. At International Super Sensors Corp, we offer all varieties of thermocouple wire, able to meet virtually any customer specification. Each thermocouple is composed of two wire legs from different metals, welded together at one end to create a junction. Thermocouples vary according to type, with each having its own individual temperature range, vibration resistance, chemical resistance, durability, and application capacity.
We manufacture all types of thermocouples, including the more common base metal products that include types K, J, T, E, and N. We also offer noble metal thermocouples that cover types B, R, and S. Thermocouples are used in a broad array of industries, markets, and applications; the wire used for construction is of vital importance in determining their temperature ranges and durability. We have a comprehensive range of thermocouple wire at International Super Sensors, listed below are thermocouples according to type:
Type K: An accurate and reliable thermocouple, the type K wiring is the most common thermocouple and can handle a wide range of temperatures:
- Thermocouple Grade Wire: -454°F to 2,300 °F, -270°C to 1260°C
- Extension Grade Wire: 32°F to 392°F, 0°C to 200°C
- Standard Tolerance: ± 2.2°C or ± .75%
- Special Limits of Error Tolerance: ± 1.1°C or ±.4%
Type J: Also very common, wiring for type J features a smaller temperature range than type K and lower lifespans at high temperatures. This wiring is similar in reliability to type K.
- Thermocouple Grade Wire: -346°F to 1400°F, -210°C to 760°C
- Extension Grade Wire: 32° to 392°F, 0°C to 200°C
- Standard Tolerance: ± 2.2°C or ± .75%
- Special Limits of Error Tolerance: ± 1.1°C or ±.4%
Type T: The wiring for type T thermocouples is typically used in extremely low temperatures settings because of its highly stable nature.
- Thermocouple Grade Wire: -454°F to 750°F
- Extension Grade Wire 32° to 392°F, 0°C to 200°C
- Standard Tolerance: ± 1.0°C or ±.75%
- Special Limits of Error Tolerance: ±0.5°C or ±.4%
Type E: Wiring for type E is extremely accurate and features a stronger signal than types K or J at moderate temperatures (less than 1000°F).
- Thermocouple Grade Wire: -454°F to 1600°F, -270°C to 870°C
- Extension Grade Wire: 32° to 392°F, 0°C to 200°C
- Standard Tolerance: ±1.7°C or ±.5%
- Special Limits of Error Tolerance:±1.0°C or ±.4%
Type N: These durable thermocouples have similar qualities to type K.
- Thermocouple Grade Wire: -454°F to 2,300 °F, -270°C to 1260°C
- Extension Grade Wire: 32°F to 392°F, 0°C to 200°C
- Standard Tolerance: ± 2.2°C or ± .75%
- Special Limits of Error Tolerance: ± 1.1°C or ±.4%
Type B: Type B is of the highest level of accuracy and reliability, and is able to withstand high temperatures and difficult conditions
- Thermocouple Grade Wire: 32°F to 3100°F, 0°C to 1700°C
- Extension Grade Wire: 32°F to 212°F, 0°C to 100°C
- Standard Tolerance: ±.5%
- Special Limits of Error Tolerance: ±.25%
Type R: This thermocouple has a high percentage of rhodium. It is able to withstand low and high temperatures with high accuracy.
- Thermocouple Grade Wire: -58°F to 2700°F, -50°C to 1480°C
- Extension Grade Wire: 32° to 392°F, 0°C to 200°C
- Standard Tolerance: ±1.5°C or ±.25%
- Special Limits of Error Tolerance: ±.6°C or ±.1%
Type S: Similar in composition to type R, the wiring for these thermocouples is versatile, used in both biotech and pharmaceutical applications.
- Thermocouple Grade Wire: -58°F to 2700°F, -50°C to 1480°C
- Extension Grade Wire: 32° to 392°F, 0°C to 200°C
- Standard Tolerance: ±1.5°C or ±.25%
- Special Limits of Error Tolerance: ±.6°C or ±.1%
